Hi! I'm trying to model a single zone building with OpenStudio. I'm trying to insert a HVAC system that works only with electricity. I added a Packadge Rooftop Heat Pump and attached to it my single thermal zone. The AVAC system is not working correctly. My knowledge in HVAC system is far to be good and some help is needed. For this simple AVAC system do I have to add other(s) component(s) to the selected HVAC system or the HVAC template provided by OpenStudio is enough to my system works correctly? Thank you
